To replace all the IC sockets you will need 4 8pin dip sockets 5 14pin dip sockets and 2 16pin dip sockets. They are all 2.54mm and 7.62mm, mine fit perfectly
I bought mine from Newark
5 x 19M1525 8pin dip
6 x 95M5018 14pin dip
3 x 19M1527 16pin dip
I also got 95Y3988 which is solder flux that worked well for me.
A good desoldering toll is necessary, I used a Hakko FR300 with good results
